Abstract

A plurality of amplifiers (102, 103) havingdifferent amplification factors are provided and areceived signals (101) and amplified output signals areall sampled by A/D converters (104, 105, 106). Aselector (107) selects, from the sampled signal, asignal from which accuracy can be attained exceedinglyand is not saturated upon sampling, so that there can beprovided an A/D conversion apparatus which does notrequire AGC control and conversion calculation of dataand can obtain desired accuracy. Selection logic canuse comparison of maximum values and logical sums ofabsolute values of the sampled values, levels which arenot amplified or the like.
